hello all,

i'm experiencing some problems with gen 27 with lots of values detailed by the following csd:

http://pastebin.com/EaNzQyBc

each table's data should be x=y, but this stops working properly with a table length of 2048 (with 4096 arguments given to gen27).  is there a limit to the number of numerical values one can supply to gen27?  does anyone have alternative method to importing large sets of breakpoint information into csound?

thanks as always,
 – ben

You allocate 4096 memory indices but fill the table with 10.000+ values, exceeding 4timesfold the maximum capacity of indices?

Can you open a ticket on github so we can investigate it? 2048 does sound very low for a limit.

thanks John.  I can confirm that my test csd now works (i'm compiling git develop on OSX).  however, there are still some oddities that I can't seem to explain.

the following table is well formed (that is to say that the x coordinates are always incrementing), yet csound complains otherwise and the data fails to load properly.  

sorry if it is a mistake on my part!

http://pastebin.com/Fgjy8HM2

ftable 99: x coordinates must all be in increasing order:
f 99     0.00  4096.00   -27.00    0.00 ...

cheers,
